Assuming the Mets don't get Manny or do get Manny and lose Cliff the Mets will be filling RF with Victor Diaz and/or Xavier Nady. If it was your choice who would you choose? A platoon could be possible but looking at their splits they don't seem to match up well in that regard.

I think this is a possible scenario, and I would generally expect a Diaz/Nady platoon in RF, at least until a clear starter emerges.

They had too... the Mets were one short on pitching and Diaz was taking up a spot on the bench with Nady hitting as great as he has been. Diaz is too young to sit on a bench, he'll play in AAA until he's needed.
